What is the Origin of Overtraining Syndrome Hormones?

This clinical term is derived from sports medicine and exercise endocrinology, recognizing the detrimental systemic effects of chronic, unrecovered physiological stress. The underlying pathology is rooted in the body's attempt to conserve energy and reduce anabolic drive in the face of persistent catabolic stress. The hormonal changes are a measurable indicator of the body prioritizing survival over performance.

What is the Mechanism of Overtraining Syndrome Hormones?

The mechanism involves chronic stress signaling, which elevates sympathetic nervous system activity and circulating cortisol. High cortisol directly inhibits the hypothalamic release of GnRH, leading to secondary hypogonadism and suppressed testosterone. Furthermore, the persistent energy deficit and inflammatory load associated with OTS can impair thyroid function and insulin sensitivity. This collective hormonal suppression compromises muscle repair, immune function, and mood regulation, perpetuating the syndrome.

Overtraining Syndrome Hormones

Meaning

Overtraining Syndrome Hormones refers to the specific pattern of endocrine dysregulation observed in athletes experiencing Overtraining Syndrome (OTS), a pathological state characterized by prolonged performance decrement and systemic fatigue that is not alleviated by typical rest. The hallmark hormonal markers often include a blunted or suppressed hypothalamic-pituitary-gonadal (HPG) axis, leading to low free testosterone, and an altered hypothalamic-pituitary-adrenal (HPA) axis, manifesting as chronically elevated or severely blunted cortisol response. This hormonal profile is a clear physiological signal of a failed adaptive response to excessive training load.
